I have an OMNI 6+ and an OMNI 7. They both put out full or near full power up
to an SWR of about 3:1. Somewhere above that they shut down completely. To me
this design characteristic is far more useful than the Jap Rigs (of which I
have several Kenwood and Yaesu) which begin loosing power above about 1.5:1!
